Which do you think guys is the best ROM from Solis in terms of battery life, Miui 8 or 9? Battery is my only concern about my Mi4C. I am now using the Miui 8 stable with sync services only for whatsapp and gmail, but I dont know if I will get extra juice if I use some developers versions of Miui9...
Also I am a little lazy to made a complete clean installation of a new ROM and restore all the apps and settings that I having now xD. Solis, have the dev ROMS the backup settings in Miui? I mean, can I made a local backup in Miui, save it my PC, made the clean installation of the dev ROM and after all restore the data again with the backup settings in Miui? or is also this feature debloated?
